5 Maintenance and care
Because the Windy Boy 5000 / 6000 can be used outdoors in places that are difficult
to access, it has been constructed for low maintenance.
In the interests of maximum yield, the operator should check, weekly if possible,
under various conditions of wind, if the displays of the Windy Boy 5000 / 6000
indicate plausible normal operation (cf. chapter 3.3.4 "Description of the operational
status" (page19)). Naturally, this information can be obtained by using one of the
communications options.
The cleaning intervals are dependent from the ambient conditions. Make sure that
enough air can flow through the fan guards. With that you can contribute to an
optimum yield of your system.
If the LEDs are so dirty that they can no longer be seen, then they can be cleaned
with a damp cloth. Solvents, abrasives or corrosive liquids must not be used!
A detailed description of how to clean the fans can be found in the installation
manual of the Windy Boy 5000 / 6000.
